Inkbird ITC-308 Digital Temperature Controller 2-Stage Outlet Thermostat Heating and Cooling Mode Carboy Homebrew Fermenter Greenhouse Terrarium 110V 10A 1100W

Below are the 4 items i purchased 3 years ago and it has worked like a charm . Total cost approx.450 (freezer was on sale). Just silicon the seams, plug the until into the thermostat, and set the thermostat for your desired temp. Mine is set for 45 degrees. I unplug the unit before I get in. To clean, I use a small fountain pump connected to a water hose to drain every other week. https://www.bestbuy.com/site/insignia-14-0-cu-ft-garage-ready-chest-freezer-white/6444379.p?skuId=6444379 https://www.amazon.com/dp/B01HXM5UAC?ref=ppx_pop_mob_ap_share https://www.homedepot.com/p/Gorilla-10-oz-Waterproof-Caulk-and-Seal-100-Silicone-Sealant-Clear-8050001/317320676 https://a.co/d/0c19gNPi

I also recommend Inkbird temperature controllers that makes fine-tuning a lot easier. It also saved my fish from freezing to death once because it has a loud alarm and woke us up in the middle of the night, it was really cold and all my fish were barley moving so if we waited until morning I bet they all would have died. I have one on every tank https://a.co/d/0gKff6nm

Heaterhttps://www.amazon.com/dp/B07573FKSG Replacement thermostat*Only if you find you need it (see below)https://www.digikey.com/en/products/detail/cantherm/A1014005/5287293?so=98295643 Temperature Controller:I use Inkbirds, when on sale they're around $25 for the non-wifi model. There are a lot of different options available, many cheaper.https://www.amazon.com/dp/B01HXM5UAC Inline power switch:I cut the heater's power cord and wire one of these in. This lets me just set the Inkbird to 60c, hide it and never think about it again.https://www.amazon.com/Inline-Switch-Appliance-Button-Indicator/dp/B0CPPGBDRS/ I use this mount on Makerworld for my P1 units, I have a model I've designed for my Snapmaker U1s that I haven't posted yet, it needs a minor modification. *The thermostat that's included with the heater trips at around 60c, and can take awhile to reset and start heating again. If this winds up being a problem (temps drop too much), you can either replace it with a bit of copper wire (don't do that) or buy a cheap replacement with a higher temperature limit for a couple of bucks. Pop off the fan cover, unscrew the old one, and screw the new one in. Super easy.

I've been using an identical model of that oven along with this temperature controller. No PID mod necessary. You'll have to nail down exactly where you need the knob to be to maintain the temp you want without getting too hot too quickly. I also have an outlet timer on it, so I can run it for 12 hours or whatever and it'll shut off on its own Temperature controller with probe https://a.co/d/02jx4iVN Mechanical outlet timer https://a.co/d/0hO3jFnA
